Module A-140 is an envelope generator, and, since it puts out control voltages, counts as one of the modulation devices in a modular system. As soon as the gate input receives sufficient voltage, the ADSR generates a variable voltage, changing in time, called an envelope. This varying voltage is out..

Module A-141-2 is the successor of the obsolete former VCADSR module A-141. Compared to the A-141 a lot of improvements and expansions have been added:common control voltage input for all time parameters (A/D/R), range switch for three different time ranges, inverted ADSR output, additional out..

Module A-150 (Dual VCS) contains two separate voltage-controlled switches.Each switch has a control voltage input, a common Out / Input, and two In / Outputs. The switches are bi-directional: they can work in both directions, so can connect one input to either of two outputs, or either of two inputs..

Module A-151 (Quad Sequential Switch) is like an electronic four-position rotary switch.It includes trigger and reset inputs, four in / outputs, and a common out / input. Each time a pulse is received at the trigger input socket, the common out / input is connected to the next in / output. After the..

Module A152 is a very useful switching and T&H module. It combines a voltage addressed 1-to-8 multiplexer and 8 fold T&H that can be used as kind of an analog shift register too. The active in/output is displayed by a LED. The digital output of the currently addressed step outputs "high". Th..

       Module A-154 is a supplement to the A-155 Analog/Trigger Sequencer module. It offers a lot of new features that are not available in the basic control unit of the A-155. The A-154 is used to replace the control unit of one or tw..

Analog and Trigger Sequencer, 2 rows of 8 steps with knobs and 2 rows of 8 steps switchesFeatures of the analog rows (knobs):8 potentiometers (knobs)lower row: Scale (knob), voltage output range 0 ... ~ +6,5Vupper row: 1V/2V/4V (octave range switch for exact VCO control), voltage output ranges ..

  Module A-156 is a Dual Control Voltage Quantizer. A quantizer converts a continous control voltage in the range 0...+10V into a stepped output voltage in the same voltage range (i.e. only certain voltages occur). Normally 1/12 V steps are used to obtain semitone steps. Quantizer 2 o..

A-157 is a trigger sequencer subsystem that is used to generate up to eight trigger signals controlled by a 8x16 LED/button matrix (some customers call it "Miniature Schaltwerk" as it is based on the same matrix as the no longer available Schaltwerk). The system is still in the prototype state...

Module A-160 is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses. The Trigger input will take clock signals from, eg., an LFO, MIDI sync, or the gate from a MIDI-CV interface.At the outputs, you have access to the sub-divi..
